Reaction of 1-methyl-2-methylsulphonyI-5-nitroimidazole (2) with pyrrolidine, piperidine and morpholine affords the amines(3a-c)(=9a-c) respectively in low yields, the reaction failing with other bases tried. Analogues (9d-t) have been obtained more readily by nitrating imidazoles (8), which are sy'nthesised from thioureas (5) of cyclic secondary amines through the S-methylisothioureas (6) and the guanidinoaeetals (7).
